Itemized deductions are recorded on "Schedule A".
Schedule A is required in any year you order your deductions. The calendar has seven classes of costs: therapeutic and dental costs, charges, intrigue, blessings to philanthropy, loss and burglary misfortunes, work costs and certain incidental costs. Starting in 2018, different costs are never again deductible. Every one of these classifications has diverse prerequisites and restrictions on the sum you can deduct.
